AKG Headphones

i gave three stars because i cannot use the Persona-Fi option, for whenever i try to use it, it keeps telling me to move to a quiet area. trust me i have moved to a very well sound proofed studio just to do this, but still the same issue. it's really frustrating now. i have seen other users complaining about the same without any resolution from AKG. it seems that you don't really care about the users.

Just got the akg n9 hybrid, great headphones but this app needs some serious work before I recommend these to someone. Other than the fact that the app randomly disconnects. The personi-fi setting forgets everything the moment you switch back to high-res audio so you'll have to do the 16-step test again. The test itself is also flawed, some tone ranges I was able to hear completely, and instead of auto registering at the end of the range it starts the test over again...

These are by far the worst pair of headphones I've ever used. Nice compact design, but swipe features are extremely difficult to execute... And now it seems the right side (which controls everything) is no longer accepting any commands. The app is very basic and has limited abilities. DO NOT WASTE YOUR MONEY. If you already purchased this trash, I'm sorry.
